SAFETY PIN.

Application filed May 4, 1923. Serial No. 636,718.

To aZZ whom it may concern:

Be it known that I, JACOB J. SILVERMAN, citizen of the United States of America and a resident of Boston and county of Suffolk and Commonwealth of Massachusetts,

- administrator of the estate of NATHANIEL L.

SILVERBIAN, late a citizen of the United States, and a resident of Boston, in the county of Suffolk and Commonwealth of Massachusetts, believe that the said NATHAN- IEL L. SILVERMAN has invented certain new and useful Improvements in Safety Pins, of which the following is a specification.

This invention relates to garment fasteners and more particularly to that class generally known as safety pins. An object of this invention, is to provide a safety pin that may be subjected to severe transverse and longitudinal strains, and so constructed as to yield to the said strains in such manner, that the pin point will not be dislodged from its retaining and protecting sheath.

A further object of the invention is to so arrange the pin shank with relation to the spring coil that the bend of the coil adjacent the portion of the garment that is pierced by the pin will act as a guard to prevent that portion of the garment from being forced between the said shank and the adjacent coil of the spring and held therein.

A further object of the invention is the production of a safety pin which by reason of its structure will lie fiat against the garment to which it is attached this being espe cially true when the portions of the garment thus secured are subjected to strains as would be the case in fastening bandages or when used to fasten the clothing of babies.

To the attainment of the above objects the invention consists in certain novel features of construction illustrated in the accompanying drawing.

Of the drawings:

Figure 1 represents an elevation of a safety pin in the position it would assume when attached to a garment.

Figure 2 a similar view showing the position the pin will assume when subjected to severe longitudinal strain.

Similar characters refer to similar parts in the drawing.

Referring to the drawings:

The wire 10 at one end thereof has secured thereto the usual pin retaining or pro- A spring coil 13 of one or more convolutions is formed at approximately midway between the ends of the wire 10 as usual.

In the drawings the safety pin is shown in attached position as it would appear on a garment with its point 12 in retained posi tion in the sheath 11.

The portions of the wire 10 between the sheath 11 and the coil 13 which constitute the body portion 14 of the safety pin and the pin shank 15 are bowed or arched in approximately the same plane and direction and are preferably normally parallel and concentric as shown in the drawings.

WVhile the drawings show both the body portion and the pin shank bowed or arched it is obvious that the body portion may be made straight if desired without departing from the spirit and scope of the invention.

The curvature of the pin shank is such as to compel the safety pin to lie flat against the garment to which it may be attached and therefore it is considered an important feature of the invention.

It has also been found that the strains to which the ordinary safety ins are subjected, tend to. and in fact do 0 tentimes lengthen the distance between the coil and the sheath by the bending of the body portion of the wire, to such extent that the point will almost invariably free itself from the sheath and become a source of danger to the user.

By arching the body portion 14: and especially the pin shank 15 as shown it has been found that the above mentioned strains conveniently serve to straighten the pin shank 15 and move its pointed end 12 farther into the sheath 11 rather than withdraw it therefrom. This action will be readily understood by viewing Figure 1 of the drawings.

Figure 2 of the drawings shows the safety pin when in use to hold two edges or ends of a garment in place and herein the pin is shown as being subjected to severe longitudinal strain. As shown the pin body 14 and shank 15 have been considerably straightened by reason of the said portions yielding to the strain while the point 12 remains in approximately the same relatire position with the sheath 11, with a tendency to further enter the said sheath.

It will be understood that a safety pin of this description made with the same kind and size of wire will have greater strength than the straight body and shank pins at present in use and will possess great flexibility which is entirely lacking in the present pins. A very annoying feature in connection with the safety pins at present in use is the readiness with which the goods will become jammed between the coils of the spring when attaching the pin to a garmerit.

in the present invention the pin shank 15 is so arranged with relation to the coil 13 that the bend 16 of the coil 13 acts as a stop for the goods and it is impossible to force the goods beyond it to become jammed between the coils as heretofore.

The shank 15 leaves the coil 13 by a somewhat sharp turn 1'? and crosses the coil in an approximately radial line so that the bend 16 extends each side of the shank 15 and effectually prevents the goods from being forced along the shank 15 and between the coils of the spring coil 18.

It is believed that the invention will be understood from the foregoing description and the claims hereinafter given.

Having described the invention 1 claim:

1. A safety pin of the class described comprising a round wire, a portion of which is bent to form an arcuate body portion, a portion coiled to form. a spring, and another portion bent to form a reverse curve and arranged approximately parallel to said body portion where-by said safety pin is compelled to assumeaposition flat against the article it is engaged with; a sheath fast to the free end of said body portion; and a piercing point formed at theifree end of said reverse curve.

2. is safety pin of the class described, comprising a round wire of approximately uniform gauge, a portion of which is bent to form an arcuate body portion; another portion being appreciably bent to form a reverse arcuate pin portiom whereby said safety pin is compelled to assume a position fiat against the article it is engaged with; a coil formed in said wire and intermediate said portions, said portions being arranged in approximately parallel relation a sheath fast to the free end of said body portion; and a piercing point formed at the free end of said pin portion.

3. A safety pin of the class described, comprising a round wire of approximately uniform gauge to form a body portion and having a spring coil formed therein substantially midway of its length, and having a portion thereof at one side of said coil bent to form a decided arc, to form pin portion, said pin portion extending from said coil in the general direction of and substantially alongside of said body portion, whereby the free ends of said wire may be brought into close proximity with each other, and said safety pin is compelled to assume a position flat against the article it is engaged with; a sheath secured to the free end of said body portion; and a piercing point formed at the free end of said pin portion.
